test: unit tests for Ozonetel integration, caller resolution, team, missed calls

48 tests across 5 new spec files, all passing in <1s:

- ozonetel-agent.service.spec: agent auth (login/logout/retry),
  manual dial, set disposition, change state, token caching (10 tests)
- missed-call-webhook.spec: webhook payload parsing, IST→UTC
  conversion, duration parsing, CallerID handling, JSON-wrapped
  body (9 tests)
- missed-queue.spec: abandon call polling, PENDING_CALLBACK status,
  UCID dedup, phone normalization, istToUtc utility (8 tests)
- caller-resolution.spec: phone→lead+patient resolution (4 paths:
  both exist, lead only, patient only, neither), caching, phone
  normalization, link-if-unlinked (9 tests)
- team.spec: 5-step member creation flow, SIP seat linking,
  validation, temp password Redis cache, email normalization,
  workspace context caching (8 tests)

Fixtures: ozonetel-payloads.ts with accurate Ozonetel API shapes
from official docs — webhook payloads, CDR records, abandon calls,
disposition responses, auth responses.

QA coverage: TC-MC-01/02/03, TC-IB-05/06/07, backs TC-IB/OB-01→06
via the Ozonetel service layer.
